The Dolphins released defensive tackle Isaako Aaitui and safety D.J. Campbell on Monday evening, creating two vacancies on the team's 53-man roster.

It is possible Aaitui and Campbell, who were both promoted up from the practice squad earlier this season, could return to Miami's developmental unit. Both players would need to clear waivers on Tuesday before returning to the team.

Aaitui played in four games and contributed three tackles this season. He was inactive for Sunday's 20-16 loss to the Panthers.

Campbell was one of five safeties on the team's 53-man roster. When Chris Clemons suffered an injury late in the fourth quarter of last Sunday's game Campbell replaced him as the Dolphins free safety because Jimmy Wilson was manning the nickel spot.

What General Manager Jeff Ireland plans to do with the two roster vacancies could have a lot to do with the ankle injury Daniel Thomas suffered on Sunday.

Watkins is still on the team though.

I believe he was one of our draft picks a year or 2 ago.

His name sounds familiar. Maybe he was on our prac squad? I don't know. What position?

And getting leap frogged by practice squad players.
